Abstract

The developed and ordered mesoporous carbon nitride, possessing a large surface area, uniform pore size, and a 2D accessible framework, shows improved activity for photochemical reduction of water with visible light in the presence of Pt as a cocatalyst and electron donors. The ordered mesostructure allow for easy assembly of catalytic cofactors in the structure, where natural photosynthetic chromophores and their redox cofactors are coassembled in nanosized protein channels embedded in cell membranes. The photocatalytic activity was evaluated by photochemical reduction of water in the presence of an electron donor with visible light and evaluated under SEM and TEM images. The structure was found to be partially promising as a host semiconductor scaffold for the design of hybrid visible-light photo-catalysts, as it enables the convenient functionalization by surface reaction or deposition which is per definition always in closest proximity to the active sites of the catalytic support.
